It is hard to tell how much a person can get for selling 30 games at Gamestop. It really all depends on ha games you are wanting to sell and what shape they are in.
in gamestop On Ebay your can sell the games and the PS2 as a Set or as individual items. Mostly a used PS2 will not get you much money and can be used as a DVD player on an extra TV in many Homes.
If you trade in a game for another game you normally have to pay them some.
As of Dec 2011, older model 15 trade in ,slim 25 Trade in.
About $20-30

I don't think they buy PS1 anymore at gamestop
Always depends on the game title and current inventory
